摘要：

The behaviour of iron atoms during the unlubricated sliding of Al-Si alloys against a steel countersurface has been investigated. Mossbauer spectroscopy and X-ray diffraction have been used to identify the form of the iron that was present in the mostly aluminium surface layers that were formed by the wearing process. The iron was found to exist mostly as elemental iron, 57-80 at.%, with a significant amount as Fe2+, 14-29 at. %. The Fe2+ was probably a finely dispersed amorphous iron oxide which, it is suggested, increases the stability of the surface layers by pinning the grain boundaries,
